Ride at your own risk

I've never been a big fan of rides, especially after some bad experiences in the gravitron, but I'd like to try the roller coasters. After all they should be pretty safe right? Well maybe not, because they do not have regulations like motor vehicles, some bad stuff can happen like this little girl who had a partial hepatic amputation (i.e. her liver ripped apart), by a roller coaster crash.

How often do accidents like that occur? According to this study of 1994-2004 , more often than you think: "Forty people, ranging in age from 7 to 77 years, were killed in 39 separate incidents. Twenty nine (73%) deaths occurred among roller coaster patrons. Eleven fatalities resulted from external causes related to injuries from falls or collisions. Eighteen people died from medical conditions that might have been caused or exacerbated by riding a roller coaster; 15 were the result of intracranial hemorrhages or cardiac problems. Eleven (28%) deaths involved employees; all were caused by injuries."
